Dear Colleagues and Linuxaudio.org Consortium Stakeholders,
It's been a long time since we used these lists to communicate and
coordinate the Linuxaudio.org consortium. This was in part because the
community has experienced a steady growth both in terms of resources and
their support through Virginia Tech. Since the server was migrated to
Virginia Tech almost 12 years ago, the server traffic and its services
increased by several orders of magnitude. In 2006 we had only a couple
of vhosts with thousands of monthly hits and minimal bandwidth. In
contrast, by January 2018 those numbers grew to over 10TB of monthly
traffic with over 7 million hits spread across 40 vhosts.
As you may be by now aware, the server was severely compromised at the
end of January which warranted complete reconstruction. It appears one
of the community members' SHA keys were stolen and used to access the
terminal upon which the hacker exploited a bug in kernel to gain root
access. The good news all the data was safely backed up and recovered.
This hack was made possible in good part due to understaffed nature of
server admins. As a result a decision was made to migrate server, thanks
in good part to the hard work of Jeremy Jongepier, to the cyso.net
servers in Europe where it is anticipated to have a more regular support.
After almost 2 weeks of downtime, the end result are better hosting and
more bandwidth for the community. This, however, also marks an important
milestone in this essential community resource. Namely, I believe it is
time to once again mobilize the management group and to establish an
advisory board or a steering committee that will help steer the
consortium and jointly explore ways to provide better and more
consistent support, ensure we offer up-to-date information, to grow the
resources, their visibility, and footprint, as well as consider
establishing a foundation that may help facilitate and support critical
programs, including the LAC conference.
With this in mind, I invite those who are still active in the community
and are receiving this email to voice their thoughts on this matter for
the purpose of identifying optimal next steps. Thank you.
Best wishes,
Ico

They will most likely want to see an actual registered non profit before
they commit to provide any funding. Samsung might be a good start as they
have already implemented JACK as part of their custom Android "pro"
musician framework. The Linux Foundation will have direct contacts for
corporate sponsors interested in supporting Linux Audio Consortium if any
exist.
A few questions:
- What is the target funding amount?
- Who will be in charge of assigning the funds for payments?
- What will the funds be specifically used for?
- Another option might be simply asking the community to donate
cash/crypto. There must be a few Linux Audio folks who made some decent
returns from btc/eth by now.
- To really take ownership of the funding issue the Consortium can
undertake an Initial Coin Offering (ICO) by creating a Linux Audio Token
which can then be traded on the open crypto market. For example, an
Ethereum ERC20 smart contract can be generated with an initial mint of ex
10 million coins. Linux Audio supporters can purchase Linux Audio Tokens
during the ICO for a discount price of ex. 25c/token. After the ICO the
tokens can be traded on the global crypto market.
If the Consortium reserves 1 million tokens for future use and sells the
remaining 9 million that will provide upto :
9,000,000 x 0.25 = USD$2.250,000
which can be converted to cash/alt coin or used to pay developers directly
with LAT.
The Tokens will not be considered a security because they there will be no
implied returns. Linux Audio folks will simply be able to assist with
funding the Consortium and then optionally speculate on the value of the
tokens on the open market.
If the ICO option is something that the Consortium is interested in I am
happy to assist with the setup process. I would rather the Linux Audio
Consortium could stand on it's own merit without being subject to any
corporate oversight.

Dear all,
We just enabled all mail services for linuxaudio.org again. All mailing
lists are working again and mail can be sent and received for the
linuxaudio.org domain.
A short recap of what happened is that linuxaudio.org got compromised on
January 29th, probably with a compromised private SSH key or password
from an account with shell access. The attacker checked the kernel, saw
that it was vulnerable to Dirty COW¹, pulled in an exploit and got root.
This was quickly discovered by the IT department of Virginia Tech
University that disconnected the server from the internet and started a
forensic investigation procedure. As part of their IT security policy
the server had to be reinstalled and everything had to be set up from
scratch again. In the meanwhile I built an alternative setup and after
some discussion we agreed on moving linuxaudio.org away from the
Virginia Tech server.
So linuxaudio.org got a new home after 15 years at Virginia Tech². We're
very, very thankful that we could host linuxaudio.org on their servers
and we can't stress enough how grateful we are for all the work that has
been done on the side of Virginia Tech after the hack.
linuxaudio.org now lives at Fuga³, a fully open source OpenStack⁴ cloud
based in The Netherlands. Fuga is part of Cyso⁵, the company I work for.
The linuxaudio.org ecosystem now consists of three separate servers, a
web server, a mail server and a storage server. We rebuilt everything
with portability and scalability in mind with a strong focus on
security. You can never prevent passwords or SSH keys getting into the
hands of hackers but we'll try to keep the servers as up to date as we
can to narrow down the attack surface as much as possible.
A big thank you to all those who helped out! It was quite a ride but it
seems as if most part of the linuxaudio.org ecosystem is accessible
again. If you find any web pages, downloads or other bits and parts that
don't work properly then please let us know so we can take a look at it.
Many thanks in advance and also many thanks for bearing with us!
Best,
Jeremy Jongepier

Hello,
today I started to go through the wiki (wiki.linuxaudio.org) to get an
idea of what needs to be done. I found some stuff to do which keeps me
busy for the next weeks.
Beside of that I think the structure of the App DB is a unhandy. Its
pretty nice because there is no other software needed. But it is not
nice to search or add new stuff. So I would like to change it.
What I imagine is a database with an interface to search through and
with more data fields like "lv2 plugin", "lv2 host", "dssi plugin" and
some more. To achieve this i think there would be an database backend
needed.
So here some questions:
What do you think? Is this necessary and useful?
Is it technically possible on the current web space?
Right now its just an idea I want to discuss, until this is finished i
will work on updating the content of the wiki.

The 22nd International Conference on Auditory Display (ICAD 2016)
Australian National University, Canberra, July 2-July 8 2016
CALL FOR PAPERS, POSTERS, SONIFICATIONS, INSTALLATIONS,
COMPOSITIONS, WORKSHOPS, PANELS AND DEMONSTRATIONS
Co-chairs:Dr David Worrall, Australian National University and
Dr Stephen Barrass, University of Canberra
Please check the conference website for updates:
http://icad.org/icad2016/
ICAD is a highly interdisciplinary academic conference with relevance to
researchers, practitioners, musicians, and students interested in the
design of sounds to support tasks, improve performance, guide decisions,
augment awareness, and enhance experiences. It is unique in its singular
focus on auditory displays and the array of perception, technology, and
application areas that this encompasses. Like its predecessors, ICAD
2016 will be a single-track conference, open to all, with no membership
or affiliation requirements.
ICAD 2016-the 22nd International Conference on Auditory Display-will be
held at the Australian National University in Canberra, Australia, from
July 2 to 8, 2016. The conference venue is the ANU School of Music, in
the downtown centre of Canberra. Workshops and the graduate student
ThinkTank (doctoral consortium) will be on the weekend of July 2 and 3,
before the main conference.
Note that ICAD is back-to-back with the conference on New Interfaces for
Musical Expression (NIME) which will be held in Brisbane the following
week, so international attendees can attend two international
conferences for the one trip to Australia!
THEME: SONIC INFORMATION DESIGN
The designed world is rapidly replacing the natural world. Design has
been called the "third culture" and has been distinguished from the
Sciences and Arts by Nigel Cross in terms of
* /things to know/: the natural world in science, human experience in
art, and the artificial world in design.
* /ways of knowing/: rationality and objectivity in science,
reflection and subjectivity in art, and imagination and practicality
in design.
* /ways of finding out/: experiment and analysis in science, criticism
and evaluation in art, and modelling and synthesis in design.
This year's theme - Sonic Information Design - has the aspiration that
artificial sounds may be designed to make the world a better place. Like
other design disciplines, Sonic Information Design takes a synergetic
user-centred view of the relationship between artefacts, those that are
affected by them, and the social contexts in which they occur. A Design
orientation pays particular attention to the phenomenology of user
experience - including physical, cognitive, emotional, and aesthetic
issues; the relationship between form, function, and content; and
emerging concepts such as fun, playfulness and design futures.
Practice-based research is considered as a generative process of
exploration, speculation and discovery, with outcomes that can be
provisional, contingent and aspirational, while aiming for richer, more
situated understandings that lead to the advancement of knowledge and
the proliferation of new realities.
Sonic Information Design draws on theoretical approaches from multiple
disciplines to guide hypothesis testing at multiple points during an
iterative process -what Bill Gaver calls "humble theory". Sonic
Information Design recognises usefulness as critical for evaluating
artefacts, and the perceptual alignment with data characteristics as
critical for effective designs.
ICAD 2016 invites contributions that take a design approach, introduce
design theory and apply design methods to Auditory Display and Data
Sonification, with a view to building a conceptually robust foundation
for Sonic Information Design.

All,
As some of you may be already aware, this past December I was notified
our current virtual server that hosts a broad array of outreach
services, including these mailing lists, will be decommissioned at the
end of this month. Since, I've been working on securing the
infrastructure and ongoing support onto a brand new physical blade. I am
pleased to report we are at the very end of what has proven to be a
fairly intense journey (needless to mention I learned a lot more than I
ever wanted to about sysadmin). Our new setup is considerably more
powerful and I am confident it will offer a significant improvement in
performance over the old one. As we enter the final stage in the porting
process, there will be a brief downtime tentatively scheduled for 11am
Eastern Time (East US Coast) tomorrow, Wednesday, January 27th. During
this time, you will experience inability to access hosted services,
including web and mailing lists. My intent is to have the transition
complete as quickly as we can do the final rsync and IP address
reconfiguration. I will let you know as soon as we've completed this
final step. Thank you for your support and understanding.
Best,

I am sorry because the question is for Android OS, but Android OS is linux kernel based, by wikipedia.

Best regards,Daniel S. F. Bruno
I am familiar with Taylor's system. My main problem is that my media
server, kodi, does not allow you to redirect the audio output stream and
I therefore must delve into the arcana of alsa and the creation of
virtual soundcard with the loopback device since kodi allows you in
setup to select an alsa soundcard. I will test the Taylor filtering
system with VLC or mplayer where you can redirect the audio output
stream from the command line.
